AUTOMATIC SHIPS PUMP AND WAVE-MOTOR.

SPECIFICATION forming part of Letters Patent No. 624,483, dated May 9, 1899.

Application filed May 17,1898. Serial No. 680,944. (No model.)

matic Ship-Pump and Wave-Motor, of which the following is a specification.

Our invention is in the nature of an automatic ship-pump and wave-motor, the object of the invention being to provide mechanism whereby the fore-and-aft motion of a ship may be utilized to operate the pump, either for the purpose of emptying the hold of leakage, pumping sea-water aboard, or for any other purpose for which a pump may be utilized, the principle of the mechanism being also applicable to motors to be operated by the waves of the ocean.

With this object in view our invention consists in the improved construction, arrangement, and combination of parts hereinafter fully described and afterward specifically pointed out in the appended claims.

In order to enable others skilled in the art to which our invention most nearly appertains to make and use the same, we will now proceed to describe its construction andzope'ration, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a perspective view of a ships pump constructed in accordance with our invention. Fig. 2 is a similar view of an apparatus of the same kind of a somewhat-modified form.

Like letters of reference mark the same parts wherever they occur in both figures of' the drawings.

Referring to the drawings by letter, A indicates the base, upon which a double-acting pump 13 is mounted, said pump being provided with an airchamber 0 and doubleended piston-rod D.

E indicates a trough mounted upon stand ards F, secured to the base A and braced by rods G, connecting the corners of the trough with the corners of the base.

H and I indicate levers pivotally mounted in brackets H and I, secured to the base A, passing upward through the trough E, widened at their upper ends, as at H and I, and pivotally connected to the outer ends of the piston-rod D.

J indicates a ball seated in the trough E between the enlarged ends H and I of the levers H and I.

The foregoing description is of a device as illustrated in Fig. 1, and its operation may be described as follows: The base A either resting upon the deck of a ship or forming part thereof, the trough E extending fore and aft, the fore-and-aft movement of the ship will cause the ball J to roll from end to end of the trough. When it rolls in one direction, it will press the lever H outward by coming in contact with its upper end H, while its movement in the opposite direction will have a similar effect upon the lever I by reasonof its contact with its upper end J. When the lever I moves outward, the lever H moves inward, and vice versa, the two levers being connected by the piston-rod D. The pump being double-acting will draw and discharge water no matter in what direction the piston D is moved by the levers, so that any motion of the ball against either of the levers will cause the pump to operate.

In the construction shown in Fig. 2 the base A, pump B, air-chamber O, and piston D will be of the same construction as that hereinbefore described. The trough E will also be of similar construction, but mounted below the pump upon the base A, the pump itself being supported upon a cross bar or beam K, secured in upright end frames L and L, provided with longitudinal slots 'M and M, through which lovers 0 and P pass, said levers being somewhat similar in construction to the levers H and I, before described, and being pivoted to brackets O and P, projecting inward from the end frames L and L. Below direction in the trough by the movement of the ship it will strike the enlarged ends 0" and P of the levers O and P and cause said levers to be oscillated on their pivots. WVhen the ball strikes the lever 0, it will press it outward, causing its inner end to move inward, push the upper end of the lever Rinward, and throwing its lower end outward and drawing the piston-rod D to the right. The opposite end of the piston rod will, through the medium of the lever S and connecting-rod Q, also oscillate the lever P, at the same time throwing its lower end P inward, ready for the im pact of the ball J when caused to move in the opposite direction by the movement of the ship. As in the former constructioi'i, the movement of either lever will cause the movement of the piston-rod, and the pump being doubleacting every such movement will cause it to drawand discharge water. When thus used as a ship-pump, the device will be entirely automatic in its oper ation. It may be placed any where on board the ship, so that the ball-trough is located lengthwise of the ship, and it will be especially adapted for use on sailing-ships or other vessels not provided with power-pumps.

T T indicate bumpers, of rubber or other suitable material, to receive and cushion the levers H I and O P at the outer end of each stroke. The ball is secured against rolling out of the groove laterally by means of railings U. The levers 0 and P may be extended, as at V V in the drawings, to form handles, so that the pump might be worked by hand, if desired. The pumps may be placedathwart ship, if desired.

As illustrated and described, the ball may be located in a trough above or below the pump, the operation being substantially the same, and the pump being capable of use as a fire-pump to draw water over the side and to pump bilge-water or leakage from the ship.

The principle of our invention may also be utilized as a wave-motor, the movement of the levers under the action of the ball serving to furnish power for any desired purpose.

Our pump or motor may also be erected alongside of piers, 850., near the shore, to furnish power. The frame, pump, ball, and

other parts may be made in any approved manner or of any desired material, and while we have illustrated and described what we now consider efficient means for carrying out our invention we do not wish to be understood as limiting ourselves to the exact details of construction shown and described, but hold that such slight changes or variations as might suggest themselves to the ordinary mechanic would properly fall within the limit and scope of our invention.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent of theUnited States, is

1. The combination with a double-acting pump provided with a piston projecting at each end, of a pair of levers, a trough through which the levers project, and a ball seated in the trough between the levers, substantially as described.

2; A double-acting pump, mounted to be carried upon the deck or other part of a vessel, in combination with a trough arranged in a fore-and-aft line with relation to the ship, a ball seated in said trough and adapted to be rolled fore and aft by the motion of the ship, a pair of pivoted levers attached to the piston-rod of the pump at each end and projecting through the ball-trough in the path of the ball, and suitable supports and braces for the trough, substantially as described.
